Abstract
Appliqu, coating, as paint replacement on aircraft surfaces, offers significant environmental benefits as well as performance and cost advantages. Pressure sensitive adhesives (PSAs) are critical components of appliqu, coatings; improvements in the thermal stability, chemical resistance and removability of PSAs are needed before appliqu, films can realize their full potential as aircraft paint-replacement coatings. PSAs require a liquid-like flow under pressure to establish contact, and a high energy dissipation capacity for peel resistance. The need to balance these two features limits the thermal stability and chemical/weathering resistance of today's PSAs. We have employed nanostructuring and hybridization principles to overcome this obstacle. Nanostructured PSAs employ the tremendous specific surface area and the nano-scale spacing of nanomaterials to realize improvements in energy dissipation, cohesive qualities, thermal stability, barrier attributes and chemical/weathering resistance. Hybrid pressure sensitive adhesives make complementary use of different PSA constituents, which retain their distinct qualities within a stabilized hybrid system, to meet demanding performance requirements at competitive cost. The Phase I project developed a cost-competitive class of hybrid/nanostructured PSAs which are stable over a broad temperature range, provide high levels of chemical/weathering resistance, and exhibit desired removability after aging for use with appliqu, coatings on exterior aircraft surfaces. The proposed Phase II (and Phase II Option) efforts will develop scaled-up processing and control capabilities for high-volume, low-cost production of hybrid/nanostructured PSAs, their transition to appliqu, films, and thorough characterization of the end product for use on aircraft surfaces.
